GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 596,258, dated December 28, 1897. Application filed January 26, 1897. serial No. 620,738. (No model.) Patented in England August 27, 1894, No. 16,295.

To all whom it may concern:

Be it known that I, GEORGE BRAY, a subject of the Queen of Great Britain and Ireland,residing at Leeds,in the county of York, England, have invented certain Improvements in Gas-Burners, of which the following is a specification, this invention having been patented to me in Great Britain August 27, 1894:, No. 16,295.

This invention relates to certain improvements in fiat-flame burners, and is more particularly suitable to hilly districts and tall buildings, inasmuch as the user can regulate them to suit any pressure sent out by the gaslighting authority, and thus obtain the highest lighting value with a minimum of gas consumed.

My improvement consists of two burners, the one screwed onto the top of the other. The gas supplied to the top burner is regu lated by the capacity of the bottom burner, which preferably should be What is known as the union-jet.

The top burner I make'in union-jets, slit unions, and bats wings Within the upper burner, and immediately above the bottom burner when screwed together I place a stuffing medium consisting of layers of muslin or other suitable material for the purpose of steadying the gas after it has passed the bottom burner. The bottom burners are made with a capacity of from one-half cubic foot to that of eight cubic feet per hour. The top burners are of a capacity of two cubic feet to twelve cubic feet per hour. The user is thus enabled to select the bottom burner of such capacity as is suitable to the pressure of gas at the altitude at which it is burned. Having selected the bottom burner the user will select a top burner which will give the thickness of flame, pressure being considered, at the point of ignition, and thus obtain the best result from the least consumption of gas.

Very little experience is required in order to determine the proper combination of top and bottom burner to suit the varying conditions of supply.

In describing my invention in detail reference is made to the accompanying drawings, in which Figure 1 represents an elevation of my improved gas-burner, and Fig. 2 a vertical section through the same.

The bottom portion Aof the burner screws to the gas-bracket, and the top of the burner is reduced in diameter. The interior at the reduced part is fitted with a perforated disk B. To the bottom burner A is screwed another burner C of larger burning capacity, and at the base of the said burner is a perforated diaphragm D. The space E between the diaphragm and the upper portion of the burner is filled with a suitable stufling medium consisting of layers of muslin or like material, through which the gas passes, thereby regulating the fiow or current and steadying the pressure before it arrives at the point of ignition in the top burner C.

What I claim is In combination, the lower burner-tube A threaded to engage the gas-bracket, and having a contracted upper portion, the perforated disk B fitted in the'mouth thereof, the burnertube 0 threaded upon the upperend of the tube A, the diaphragm D in the lower end of the tube 0 and the burner-tip in the upper end of the tube 0, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
